However, the roll out of the update came in stages. Initially, only a few of the listed Xperia devices received the update but once the release was proven successful, the Android 5.1.1 Lollipop eventually came to the rest of the smartphones and tablets on the list.
Typical with an OTA update, users were able to see it through a notification so they were able to manually check the system updates of their respective devices in the Settings menu.
Android 5.1.1 Lollipop was a big update so those who decided to download it via mobile data definitely incurred a huge cost. Sony actually recommended to users that they use a Wi-Fi connection to download the firmware update.
After the release of the Android 5.1.1 Lollipop, Sony has subsequently released the Android 6.0 Marshmallow developer preview build for 12 of its Xperia devices, which was consistent with its two-tiered approach to equip its devices with the latest mobile operating system from Google.
Unlike in the release of the Android 5.0 Lollipop in November last year when Sony’s smartphones and tablets got it quite late, it will not be the case with the Android 6.0 Marshmallow as it is likely that the first 12 Xperia devices will be among the firsts to receive the latest mobile OS from Google.
